How do I get a variable in a URL, but when the URL is saved in a PHP variable?

Question

$url= "justfwalk.it?uid=12";

How can I get the variable "uid" from this string?

Is there is an easier method than looking for it's position and trimming the string?

@Brad Note: This function doesn't work with relative URLs. — Naftali

@Neal, but it is trivial to concatenate a protocol and hostname to the front to use this function. Or, split on ? and use php.net/manual/en/function.parse-str.php — Brad

How about parse_url and parse_str?

<?php
$params = array();
$url= "justfwalk.it?uid=12";
$url_parts = parse_url( $url);
parse_str( $url_parts['query'], $params);
echo $params['uid']; // Outputs 12

See it in action

Sure, use parseurl

<?php
$url = 'http://localhost/'.$url;
print_r(parse_url($url));
?>

list($html, $get) = explode('?', $url);
$get = explode('=', $get);
print_r($get);
